History And Uses Of Wind Power As An Energy Alternative / Documentary Video
Wind As An Energy Alternative / Educational video. Department of Energy. Produce by the Solar Energy Research Institute. Wind: An Energy Alternative. This program looks at the history and uses of wind power, used for centuries by humans to move boats, pump water and grind grain including discussions on efficiency, problems in the urban environment, experimental systems and windmill use across the United States. Producer: Department of Energy. Creative Commons license: Public Domain.
Surprisingly good short film about wind energy. What makes it valuable is the interviews with Marcellus Jacobs (a builder of wind turbines in the 1930s) and Ted Finch (whose efforts got the concept of net metering legally acceptable in the US). It’s interesting to note that one of the people listed in the credits, Paul Gipe, is still active in the industry. He’s now a leading author on the subject. His website is http://www.wind-works.org

The Combined Power Plant – 100% from renewable energy
http://www.unendlich-viel-energie.de
The secure and constant provision of power anywhere and at anytime by renewable energies is now made possible thanks to the Combined Power Plant. The Combined Power Plant links and controls 36 wind, solar, biomass and hydropower installations spread throughout Germany. It is just as reliable and powerful as a conventional large-scale power station.
The Combined Renewable Energy Power Plant shows how, through joint control of small and decentralised plants, it is possible to provide reliable electricity in accordance with needs. The Combined Power Plant optimally combines the advantages of various renewable energy sources. Wind turbines and solar modules help generate electricity in accordance with how much wind and sun is available. Biogas and hydropower are used to make up the difference: they are converted into electricity as needed in order to balance out short-term fluctuations, or are temporarily stored. Technically, there is nothing preventing us from 100 per cent provision with renewables.
The Combined Power Plant is an initiative of the companies Enercon GmbH, Schmack Biogas AG and SolarWorld AG, and is supported by many partners from the renewable energy sector.

MWTT Maglev Wind Turbine
http://www.maglevwindturbine.com
Demo CGI for proposed 2GW Magnetic Leviatated wind Turbine.
*Efficient Frictionless Power Generation with less maintenance, compared to HAWT.
No oil change or replacement of the bearings, gears.
Since, MAGLEV does NOT require such.
** Current bearing technology has forced wind turbine designers into horizontal spindle three bladed wind turbines. In this design the huge blades are connected to a spindle in the center. The bearings that support the spindle and control the pitch of the blades (which can be hundreds of feet long) see huge pitch-moment loading, some of which is manifest as torque energy that is focused through the center spindle. The target speed for the spindle is 18 or 20 rpm and the bearings holding the spindle are mounted in a huge casting which also contains a large gearbox stepping the speed up to 1800 to 2000 RPMs which allows for the proper surface speed relationship between the coils and magnets. It is necessary to invert or condition the current, which is expensive. This gearbox is full of many large bearings, gears and castings; for a 2 MW turbine the gearbox can easily weigh 30 tons. This gearbox needs to be mounted on the top of a pole more than 150 feet in the air and be able to support the turbine blades under full-force wind conditions.
***MAGLEV Power Generation, the pitch moment ratio is closer to 1-to-1 then the 100-to-1 as with a horizontal spindle design.

$1 portable, collapsible solar hot water collector
Making hot water using unmodified trash bags (which were later used for their intended purpose). You can’t beat the ROI on these DIY solar collectors. In cold, cloudy or windy climates, an additional layer of plastic can be put over the top to hold the heat in like a greenhouse. Some day I will replace these with an inclined box and a toilet valve filler, complete with shower head.

Plug-In Wind Power!

Fast Company Magazine has this to say about the Jellyfish:
http://www.fastcompany.com/blog/anya-kamenetz/green-day/google-checks-out-pc-renewable-energy
Jellyfish Wind Power Concept:
What if you could plug renewable wind energy into the wall just like a blender or a toaster? Instead of using power, a wind appliance actually generates it!

Smart-Grid Enabled:
With onboard Wi-Fi/WiMAX the Jellyfish is also smart-grid enabled. Today, wind and solar-powered homes are operated as autonomous points within the local electrical grid. However, they are an overlooked, yet important electrical power resource. If instead, each were harnessed collectively and tied interactively with the local utility grid as a Point-to-Grid (P2G) power generator, or even regulator, considerable economic, environmental and system reliability benefits are possible. By itself, each of these power sources is indeed small in its impact on the power system. In the aggregate, however, the economic value of P2G power is significant, more than enough to offset the initial cost of installing the required control hardware and integrating these systems with the local utility grid. Equally important, the necessary regulatory and energy distribution infrastructure, and hardware components to enable a number of different types of P2G-based systems are already in place today. The convergence of existing distributed electric power and Wi-Fi/WiMAX technologies creates an emerging market opportunity for technology and service providers to enable and accelerate the introduction of various types of P2G-enabled power generation.

Solar Tower – renewable energy green global warming
EnviroMission Limited (www.enviromission.com.au) produced this 5 minute video on the pilot plant in Spain. It is an older video (2000) but gives a decent understanding of the solar tower concept.
EnviroMission, Ltd. (US Market: EVOMY, Australian Exchange: EVM) is a renewable energy developer of sustainable “green” energy solutions for the energy market. EnviroMission aims to be one of Australia’s leading producers of clean renewable energy. EnviroMission holds the proprietary rights to Solar Tower technology, a large-scale renewable energy technology based on simple fundamentals of physics — hot air rises. Solar Tower technology has the potential to offer competitive renewable energy with equal reliability to fossil fuel generators.
A single 200MW Solar Tower power station will provide enough electricity to power around 400,000 households. The energy output will represent an annual saving of more than 1,960,000 tonnes of greenhouse CO2 gases from entering the environment when compared to brown coal emissions in Victoria. The greenhouse savings equate to the removal of approximately 500,000 cars from the road. The Australian Solar Tower project consists of six distinct phases, the first two of which (project optimization and pre-feasibility commercialization) have already been completed. The third phase (final feasibility), paving the way for the implementation of the next three phases (final design, construction, and commercial operation).
